“…Metalloporphyrins are an important class of macrocyclic complexes that have shown outstanding activities for the HER and OER. However, the efficiency and conductivity of these molecular catalysts are relatively low. In order to make these well-designed molecular catalysts practical, they need to be immobilized on conductive electrode materials such as carbon nanotubes (CNTs), graphene oxide (GO), and so forth. ,, In general, there are two strategies to immobilize molecular catalysts on conductive materials.…”

“…While the CNT component with porous structure and high conductivity also promotes the electrocatalytic performance and accelerates the mass transfer to facilitate the ORR. Fine tuning of COFs layers and active sites loading while constructing COFbased CNT electrocatalyst has been investigated by Gan et al [171] As shown in Figure 10a, a class of typical COF-coated MWCNTs (COF-366-yCo@CNT-x) was synthesized through imine condensation, then Co ions were introduced to coordinate with the porphyrin units as active centers for electrocatalytic OER in alkaline environment. High-resolution TEM (HRTEM) image (Figure 10b) and the obvious lattice fringes of the COF component reveals that the COF layers are orderly stacked on the surface of the CNT with a thickness of 3-7 nm.…”

“…The main reason that COFs usually show extremely low catalytic activity is lacking of the active sites. [79][80][81] Based on this view, the most commom strategy to improve the catalytic performance of COFs for OER was decorating the active metal on the backbone in various pathways. For example, Thomas and co-workers reported a programmable strategy to synthesize 2D Co-doped COF (Macro-TpBpy-Co) with microporous and uniform macroporous structure by template-induction (Figure 10a).…”
